And again, it goes back to the debate, should you supplement with growth hormone or testosterone?

All of these activities will give you immediate benefits.

You'll bulk up more.

You'll feel better immediately.

But based on the research, it's at the expense of long-term health.

So my view of longevity, the way I treat my body is I don't burn both candles.

I have one end of the candle lit.

I'm very careful.

I don't blow on it.

But I also do enough exercise that I'm building up my muscle, but I'm not huge.

Anyone who's seen me knows that I'm not a professional bodybuilder.

But I tried to actually, here's the key, and I haven't said this publicly that I can remember.

I pulse things so that I get periods of fasting, and then I eat, then I take a supplement,

then I fast, then I exercise, and I'm taking the supplements and eating in the right timing to allow me to build up muscle sometimes.

Because you can't just expect to take something constantly and do something constantly for it to work.

And that's why it's taken me about 15 years to develop my protocol.

And there's a lot of subtlety to it.

What you want to do is to get the cells to be perceiving adversity.

Because our modern life, we're sitting around, we're eating too much, we're not exercising.

Our cells respond.
